If you are using windows and Mac ( a dual boot on a macbook), you may have noticed that time setup is always inconsistent between the two OSs. for me , always a 8 Hours difference. Why? that’s because Mac/Windows use different internal format to record the current time. UTC vs Local time (Pacific time for me, that explains the 8 hours difference.)
Here is the step to override the windows setting and make sure it use the UTC format as Mac does.
- Starup windows and setup the registry
- launch “Regedit.exe”
- open the rg key ”
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation” - Create a new key called
RealTimeIsUniversal(case-sensitive!, Type is REG_DWORD), set up value to 1 - for windows X64 version, Create an extra new key called
RealTimeIsUniversal(case-sensitive!, Type is REG_QWORD), set up value to 1
- shutdown windows and switching back to MAC
- correct your time settings
- Done. the two OS time should keep sync then
